Comment 2 Justin M. Forbes 2016-12-01 14:11:37 UTC
This issue was reported by IBM as fixed in June 2016, last listed kernel series containing this issue was 4.2 and the CVE was assigned at the beginning of March. Unless this information is incorrect, Fedora 23 has been fixed since 2016-01-20 with kernel-4.3.3-301.fc23, and Fedora 24 and Fedora 25 were never vulnerable.

Comment 3 Prasad Pandit 2017-02-01 12:09:12 UTC
That's right, this issue affects KVM on Power-8 platform; And was fixed by upstream commit

  -> https://git.kernel.org/linus/ccec44563b18a0ce90e2d4f332784b3cb25c8e9c

Which is merged in the upstream kernel from 4.5 release.

Closing this bug as fedora kernels are not affected.
